Kazom is a 3,000 year old genie. In order to conserve power and thereby extend his life, Kazom does as little magic as possible. He is bound in the form of the Clark family's cat and mostly just lays around Melvin's Room.

Red was a boy until a new genie tried to get Melvin a girlfriend. That's when the genie turned Red into a girl so Melvin could practice talking to girls, and forgot to turn her back before disappearing. Red is hopeful that her situation is only temporary.

No, it the other way around. Red was complaining that her boobs were too big, because, they didn’t fit into her bra anymore and Melvin inadvertently answered Red request and gave her smaller boobs that did fit in her bra. Red probably had DD Boobs, before Melvin honored her request for smaller boobs. But, now she has a C Boob or possibly a B Boob size. It was a major size drop, that why Ida knottiest it and thought it was just her imagination. That is until she now find out there magic that can cause that to happen.

It’s pretty likely that the escaped Djinn (currently presumed to be the infamous Blue Djinn) is going to be looking for revenge, so he’ll be after Genie Lords–particularly Guano, who is credited with having imprisoned him.
